Energy Optimization Analysis Method in Revit
From the initial concept and detailed design to the operation of both existing and new buildings, energy optimization analysis offers clear guidance to help the entire design team enhance a building’s energy performance. It is highly recommended to regularly perform energy optimization analysis throughout the building model’s entire project lifecycle to continuously improve energy efficiency.
In Revit, you can access this feature under the Analysis tab in the Energy Optimization Analysis panel, which includes the following functions:
- Location
- Create energy model
- Generate
- Optimization
- Energy settings
You can create an energy model using building elements and mass elements. Below is an overview of the process, including a video demonstration.
Energy Analysis Workflow:
- Set the model location
- Configure meteorological stations for analysis
- Verify energy settings
- Create and analyze energy models
- View analysis results in the Insight panel
The energy analysis process consists of two main steps: first, generating an energy model from the design geometry, and then using Autodesk Insight to evaluate how design changes impact energy performance.
Start by setting the model location if it hasn’t been configured yet. Go to the Analysis tab and click Location. In the dialog box, drag the pushpin on the map to your project location or select a city from the default list. You can also choose the weather station closest to your site, though keep in mind that microclimate conditions may make a nearby station less ideal. When finished, click Confirm.
Before creating the energy model, ensure that the energy settings match your design intent. Under the Analysis tab, select Energy settings. Typically, the default settings are sufficient to generate robust energy models. For detailed descriptions of each option, consult the online help. Be sure to set the Mode parameter to specify whether you are using building units, mass units, or both for the analysis. Click Confirm to save your settings.
Next, click Create energy model on the Analysis tab. In the dialog box, select Create an energy analysis model. The generated 3D view will show the energy model, allowing you to verify that the geometry and height meet your expectations.
Once the energy model is created, you can upload it to Autodesk Insight for analysis. Click Generate on the Analysis tab to send the model to the Insight service. If you modify the model geometry after creating the energy model, you have the option to update it or continue using the existing one. In this example, since no changes were made, the original model is used.
After uploading, you will receive an email once the analysis is complete. To view the results, navigate to the Analysis tab and click Optimize to open the Insight panel. This panel displays various aspects of the building’s energy efficiency.
To explore how design changes affect energy performance, select an aspect and click the Flip icon. For example, adjusting the window-to-wall ratio on the north wall is demonstrated here. The triangle on the chart marks the current ratio, while other points indicate potential alternatives.
By modifying elements like window shading devices or glass types on the north side, you can observe their impact on overall energy efficiency. Click on the chart to experiment with hypothetical changes and see how they influence energy costs. Adjust the arrow indicator to define the desired range and watch how construction costs and energy savings respond. The dial markings show target levels for energy efficiency.
By iterating through different design configurations on the Insight panel, you can identify changes that significantly boost the building’s energy performance.
Tip: Energy Optimization for Revit requires signature authentication. To use this feature, you must log in to Revit with an Autodesk account that supports signature authentication. Note that some BIM administrators may disable certain toolsets based on company policies before software deployment. If you need access, please inform your BIM administrator and ensure that the energy analysis tools and user interface options are enabled.
